I looked through my wishlist and the sale and here's what I see:
They Bleed Pixels ($3) - Good price, but I bet this is in a bunch of bundles before xmas.
The Walking Dead ($15) - ok price, but it's Telltale so it'll be like $2 in a year
I Am Alive ($11) - Wow, $4 off. Yawn. Will pick up in another few months when it's at least half off.
The Darkness II ($12.50) - Still too expensive. Main game price needs to drop so 75% will mean <$10
Hell Yeah! ($7.50) - Looks cool and I liked Arkedo's indie games, but I've heard so many bad things about this game. Even from our own forum
Don't want to pay more than a buck or two for it.
Orcs Must Die 2 ($7.50) - Loved the original, but feels like I just played the first one. Will wait a year and get it for $3.75 like I got the first.
So yeah, I don't think I'm buying anything this sale. Which is ok because I just spent like $100 on $20 games in the last week or two now that deep discounts are starting.
